Vitamin D

Athletic Performance and Vitamin D – showing an increase Type II muscle fiber at optimal (50ng/mL) levels

Vitamin D Associated w/ Greater Muscle Mass – effects hypothesized from both an androgenic point of view and direct muscle receptors (VDR)

Vitamin D and Mitochondria – As athletes, we absolutely want to maximize density and efficiency of mitochondria

Faster Muscular Recovery w/ higher 25(OH)D Levels

I have seen recommendations of 4000ius per day, but also with the warning that everyone responds differently – a dose too small is pointless, a dose too high is harmful and can lead to toxicity of the blood.
